If you believe you have found a vulnerability in syntonyl.com or one of our products, report it through the contact form and select Cybersecurity & Resilience as the service. Include enough detail to reproduce the issue, but no sensitive data.
If you are a client and suspect an incident in a system we operate, such as unusual sign-ins, unexpected changes, or ransomware, contact us immediately through your agreed support channel and mark it urgent. Do not wipe affected machines, because evidence matters for recovery.
We acknowledge good-faith reports promptly and ask that you give us reasonable time to fix an issue before disclosing it publicly.
